<span class="command"><strong>authpasswd</strong></span> is a helper utility that generates encrypted
passwords for the
Courier authentication library.
The Courier authentication library is capable of using several different
encryption methods for storing passwords.
<span class="command"><strong>authpasswd</strong></span> issues a password prompt.
Enter the same password twice (for verification purposes).
<span class="command"><strong>authpasswd</strong></span> computes and prints the encrypted password.
The encrypted password can be inserted verbatim into the appropriate
account record that's processed by the authentication library's
<code class="literal">authmysql</code>,
<code class="literal">authpgsql</code>,
<code class="literal">authsqlite</code>,
or <code class="literal">authldap</code> module.</p><p>
<em class="replaceable"><code>method</code></em> may be set to one of the following
literals:</p><div class="variablelist"><dl class="variablelist"><dt><span class="term">crypt</span></dt><dd><p>
Use the traditional <acronym class="acronym">DES</acronym>-based encrypted password.</p></dd><dt><span class="term">md5</span></dt><dd><p>
Compute a base64-encoded <acronym class="acronym">MD5</acronym> password hash.</p></dd><dt><span class="term">md5raw</span></dt><dd><p>
Compute a hexadecimal-encoded <acronym class="acronym">MD5</acronym> password hash.</p></dd><dt><span class="term">sha1</span></dt><dd><p>
Compute a <acronym class="acronym">SHA1</acronym> password hash.</p></dd><dt><span class="term">ssha</span></dt><dd><p>
Compute a salted <acronym class="acronym">SHA1</acronym> password hash.</p></dd><dt><span class="term">sha256</span></dt><dd><p>
Compute a <acronym class="acronym">SHA256</acronym> password hash.</p></dd></dl></div><p>
If not specified,
<em class="replaceable"><code>method</code></em> defaults to the
modified-<acronym class="acronym">MD5</acronym> password encryption algorithm that's used
in Linux (note that this is different from the <span class="quote">“<span class="quote">md5</span>”</span> password
hash method).</p></div></div></body></html>
